Can someone help me out with this question

A

Step-by-step explanation:

Volume = length × width × height

10(h+3)h = 10 × width × h

width = h+3

h = width - 3

Height is 3 units less than the width

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
